Hello,
I am in the process of getting another Technics cd player for my collection.

Its a bit different from the PG440A and appears to be more detailed with more opamps etc :confused:

I have in stock:
3 OPA1642
1 LME49860
NOS (about 5 or more years old0 LM4562 - 4 of them.

I can get more of above if needed like OPA1642 or LME49860. The OPA1642 is FET, like the BA4560FT

current opamps LM833N, BA4560FT

The red plus are the opamps i think to replace, and muting removed and the filter cap near the rcas. Not sure about the classAA buffer amp, the ABC connector leads to the headphone which have their own pcb from the manual.
